Legal, Policy, and Regulation Support

Technical & Claims Support 

Groundwater, contamination, and subsurface conditions often sit at the center of claims, disputes, and coverage decisions. The challenge is not just understanding the site—it is clearly connecting field conditions to documentation, policy, and the facts at issue.

Tunnell Subsurface Consulting provides technical analysis and site evaluation to support attorneys, insurers, adjusters, and project stakeholders where groundwater and subsurface conditions must be understood, documented, and aligned with the matter at hand.

Where TSC Provides Support

• Groundwater and subsurface condition evaluation

• Contamination and PFAS-related site analysis

• Property damage and water intrusion issues

• Construction-related groundwater and dewatering disputes

• Technical review of reports, sampling data, and site records

• Situations where field conditions must be evaluated against claims or policy

• Research on complicated policy and regulatory groundwater issues

Evaluation Process

TSC follows a structured approach to ensure conclusions are grounded in site conditions and supported by clear documentation.

1. Initial Evaluation
Review of available documentation, site information, and reported conditions to understand how groundwater and subsurface factors relate to the matter.

2. Findings and Recommendations
Development of initial findings, identification of key issues or inconsistencies, and recommendations for next steps based on what is known and what requires confirmation.

3. Targeted Investigation (If Needed)
If conditions require confirmation, a limited and focused intrusive investigation may be proposed—such as probing, test pits, or field verification—designed to address specific questions tied to the matter.

4. Final Analysis and Support
Integration of findings into clear, well-documented, and defensible conclusions that align site conditions with documentation, claims, and applicable requirements.

This process is designed to reduce assumptions, define what is known versus what must be confirmed, and ensure that any intrusive work is purposeful, limited, and directly tied to the issues being evaluated.

Technical, Documentation, and Policy Support

Legal and insurance matters often require more than technical input—they require clarity in how conditions relate to documentation and policy.

TSC provides support through:

• Review of site reports, monitoring data, and project records

• Evaluation of groundwater behavior and contamination pathways

• Technical analysis of how site conditions relate to claims and reported impacts

• Support for documentation where conditions must be clearly explained

• Research into regulatory frameworks and reporting requirements as they relate to site conditions

PFAS and Groundwater Experience

TSC has experience working with PFAS-related matters, including technical analysis of contamination pathways, groundwater behavior, and site conditions.

This includes work supporting PFAS-related complaints and documentation where groundwater conditions and contamination pathways had to be clearly explained and supported.

Field + Documentation Perspective

TSC combines field experience with strong technical documentation and legal awareness.

Groundwater and subsurface issues are not just technical—they are evaluated through documentation, policy, and the facts presented in a claim or matter. TSC is built to understand those intersections and provide conclusions that are grounded in field conditions and supported clearly.

Approach

TSC does not shape findings to fit a narrative.

The focus is on identifying conditions as they exist, evaluating them based on technical understanding and field experience, and providing clear, well-supported, and defensible conclusions so clients can determine the appropriate path forward.

Closing

Legal and insurance matters involving groundwater and subsurface conditions require clarity, accuracy, and supportable conclusions. Tunnell Subsurface Consulting provides the technical perspective needed to connect field conditions with documentation, claims, and policy—so decisions can be made with confidence.
